Dent repair system and method

a technology of dents and repair methods, applied in forging/pressing/hammering apparatus, manufacturing tools, forging/hammering/hammering machines, etc., can solve the problems of reverse dents or projections, large cost of many conventional collision repair jobs, and the person performing the repair often finds himself or herself too close to the damage to accurately assess the damag

Problems solved by technology

It also accounts for a significant part of the cost of many conventional collision repair jobs.
Either way a common problem relates to overcorrection, which is generally caused by the metal being stretched or expanded by the original damage.
Thus, reverse “dents” or projections often result from PDR techniques.
Both types of tools can leave deflections from overcompensation and undercompensation, which can necessitate additional repair procedures.
However, with conventional impact tools and suction devices the person performing the repair often finds himself or herself too close to the damage to accurately assess the results.

Abstract

A dent repair system includes a hammer apparatus comprising an elongated base member with proximate and distal ends. An elongated swing member with proximate and distal ends is pivotally mounted on the base member by a hinge assembly mounted on and pivotally connecting the members at their proximate ends. A tip is mounted on the base member distal end and an impact head is mounted on the swing member distal end. The swing member is movable between a splayed position with the impact head spaced from the base member distal end and a closed position with the impact head engaging the base member distal end. A pry bar apparatus includes primary, extension and handle sections. The primary section mounts a head assembly adapted for engaging and straightening a dent. A dent repair method includes the steps of straightening a dent with the hammer apparatus and with the pry bar apparatus.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to dent repair, and in particular to a system and method for paintless dent removal (PDR) and knockdown.[0003]2. Description of the Related Art[0004]Conventional dent repair involves placing fiberglass body putty in dents and sanding or grinding the resulting surface smooth and flush. Coats of primer and paint are then applied as needed to match a surrounding, existing finish. Various tools and materials are available for performing such dent repair procedures, including hammers and other impact tools for straightening damaged sheet metal.[0005]Refinishing plays a significant role in much of the collision damage repair work done with conventional tools and techniques. It also accounts for a significant part of the cost of many conventional collision repair jobs.[0006]Paintless dent removal (“PDR”) techniques are becoming increasingly popular. A major advantage of such techniques i...
